The coffee bean transcriptome explains the accumulation of the major bean components through ripening.

ABSTRACT: The composition of the maturing coffee bean determines the processing performance and ultimate quality of the coffee produced from the bean. Analysis of differences in gene expression during bean maturation may explain the basis of genetic and environmental variation in coffee quality. The transcriptome of the coffee bean was analyzed at three stages of development, immature (green), intermediate (yellow) and mature (red). A total of more than 120 million 150?bp paired-end reads were collected by sequencing of transcripts of triplicate samples at each developmental stage. A greater number of transcripts were expressed at the yellow stage. As the beans matured the types of highly expressed transcripts changed from transcripts predominantly associated with galactomannan, triacylglycerol (TAG), TAG lipase, 11?S and 7S-like storage protein and Fasciclin-like arabinogalactan protein 17 (FLA17) in green beans to transcripts related to FLA1 at the yellow stage and TAG storage lipase SDP1, and SDP1-like in red beans. This study provides a genomic resource that can be used to investigate the impact of environment and genotype on the bean transcriptome and develop coffee varieties and production systems that are better adapted to deliver quality coffee despite climate variations.
